text: To secure phenol for aspirin production, and at the same time indirectly aid the German war effort, German agents in the United States orchestrated what became known as the Great Phenol Plot. By 1915, the price of phenol rose to the point that Bayers aspirin plant was forced to drastically cut production. This was especially problematic because Bayer was instituting a new branding strategy in preparation of the expiry of the aspirin patent in the United States. Thomas Edison, who needed phenol to manufacture phonograph records, was also facing supply problems; in response, he created a phenol factory capable of pumping out twelve tons per day. Edisons excess phenol seemed destined for trinitrophenol production.
  Although the United States remained officially neutral until April 1917, it was increasingly throwing its support to the Allies through trade. To counter this, German ambassador Johann Heinrich von Bernstorff and Interior Ministry official Heinrich Albert were tasked with undermining American industry and maintaining public support for Germany. One of their agents was a former Bayer employee, Hugo Schweitzer. Schweitzer set up a contract for a front company called the Chemical Exchange Association to buy all of Edisons excess phenol. Much of the phenol would go to the German-owned Chemische Fabrik von Heydens American subsidiary; Heyden was the supplier of Bayers salicylic acid for aspirin manufacture. By July 1915, Edisons plants were selling about three tons of phenol per day to Schweitzer; Heydens salicylic acid production was soon back on line, and in turn Bayers aspirin plant was running as well.
  The plot only lasted a few months. On 24 July 1915, Heinrich Alberts briefcase, containing details about the phenol plot, was recovered by a Secret Service agent. Although the activities were not illegal—since the United States was still officially neutral and still trading with Germany—the documents were soon leaked to the New York World, an anti-German newspaper. The World published an exposé on 15 August 1915. The public pressure soon forced Schweitzer and Edison to end the phenol deal—with the embarrassed Edison subsequently sending his excess phenol to the U.S. military—but by that time the deal had netted the plotters over two million dollars and there was already enough phenol to keep Bayers Aspirin plant running. Bayer's reputation took a large hit, however, just as the company was preparing to launch an advertising campaign to secure the connection between aspirin and the Bayer brand.
